If pre- or post-processing commands fail, what happens to the task?

When pre- or post-processing commands fail during a task execution in Informatica Cloud Data Integration, the overall status of the task is affected. If these commands are integral to the workflow, a failure in them will typically lead to the task failing as well. This is crucial because pre-processing commands often prepare the environment or data for the task, while post-processing commands might handle cleanup or important follow-up actions. Therefore, if there’s an error in either command execution, it indicates that either the necessary conditions for the task were not met or that essential subsequent actions were not completed, leading to the task being marked as failed.

This understanding is vital for troubleshooting and ensuring that pre-conditions are properly set before task execution, as well as verifying post-conditions after task completion. Execution failure in these commands signifies that the task could not fully fulfill its intended purpose, thus resulting in a failure status.
